Box-MAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 267,359, dated November14, 1882.

Application filed August 9, 1881.

To all whom it may concern l Be it known that I, HENRY MESSER, of thecity of Chicago, Cook county, Illinois, have invented a new and usefulImprovement in BOX- Nailing Machines, of which the following is aspecification, reference being had to the accompanying drawings, inwhichvFigure 1 is a front elevation of the machine. Fig. is a sideelevation. Fig. 3 is a transverse section of the gage and portion of themachine to which it is attached. Fig. 4 is a top view ofthe machine.Fig. 5 is a top view ot' a pair of the cut-oft'iingers, with a portionofthe runway for the nails and the device for stopping the tlow ofthenails. Fig. 6is a section ofthe nail-pan, taken inthe plane ofthe linea@.c in Fig. 4. Fig. 7 is a section of one of the guide-posts and themechanism operating therein, taken in the plane ofthe line w tc in Fig.2'. Figs. 8 and l() are two forms of dieholders and dies. Figs. 9 and 11are sections of the same, taken in the lines z z andy y, respectively.Fig. 12 is a view showing the mechanism for rotating the arbor whichcarries the brushes, taken on the line x .fc of Fig. 2, with the archover the ratchet, and in which the arbor is journaled, broken away.

, Like letters indicate like partsin the different figures.

Some of the main features of my present machine are embodied in thepatents issued to me July 15, 1879, and November 18,1879, and numbered217,472 and 221,844, respectively; but this machine combines thefunctions of both those described in said patents with others additionalthereto.

In the drawings, A is a hollou7 column, upon which the operating part ofthe machine is supported. The column is enlarged at the base, making itsufficiently broad to afford a solid support for the machine, andtapering toward the top, which is provided with aliange. Two slots arccut in the periphery of the column upon opposite sides, to permit theinsertion and operation of a treadle, which is pivoted in che of theslots, as seen in Fig. 2. A weight is secured to the treadle, adjustableto any point on the side of the pivot opposite the point of connectionwith the other mechanism of the machine, so that in the normal positionof the machine the end of the treadle to whichthe (Model.)

actuating force is applied will be elevated and the weighted enddepressed.

Between the column and that portion of the machine resting upon itis theshelf B, consist- 55 ing simply of a broad board placed between the twoparts and held by the bolts, which secure them together, beingperforated for the passage of the rod a, this shelf being introducedsimply as a convenience to the operator. 6o

U- C is the front elevation ot' the frame which supports the nailingmechanism, being a plain face or wall with rearward-extendin g flanges,and having therein the vertical slot c.

D is a vertically-adjustable table or bracket, 65

secured to the front of the face C by means of the bolt d and nut d',the nutbeing constructed, as shown, so that it may be easily turnedwithout a wrench. The table D is made of open or grate work, and beneathit, sliding` in grooves 7o formedin anges on its under side, is adrawer, F. Thus any nails falling upon the table D will pass through theopenings into the drawer F and be preserved from'loss.

G G are vertical guide-posts, the horizontal 7 5 arms of which areprovided with slots, through which pass bolts or set-screws, securingthem to the broad iianges extending rearward from the face U. Theseposts are provided with grooves upon their inner faces, in which recip-8o rocate vertically tubular sliding blocks H H. These sliding blocksare rigidly connected with each other by the Cross or driver bar h. Uponthe driver-bar are arranged the nail-drivers h h h', which are as manyin number as may be 85' desired.

I is a cross or pocket bar, secured to the extremities of which are thevertical sliding pieces t' t', the lower portions of which slide ingrooves in the posts G, and the upper portions 9o i in the slidingpieces t' and engaging the 95 sliding pieces at the upper ends ofthegrooves. The parts and those mentioned in connection therewith can beseen in Fig. 7. rihe sliding blocks H H are not tubular throughout theirentire length, the upper portion being solid roo except as to theopenings for the insertion of the screws h3 h3.

Inside the sliding blocks H. H, bearing against their upper portionandpressing downward upon the tops of the pieces t' i, are the spiralsprings J, which tend to force the pieces t' t' outward from the-slidingblocks H H.

Extending rearward from the sliding blocks H H are two arms, h4 h4, Fig.2. Attached to these arms, and extending vertically downward therefrom,are the rods (t3 a3, which are secured in the extremities ofthecross-head a2, to the middle ot" which is attached the rod a',connecting with the treadle.

rIhe operation of the parts now described is as follows: Upon depressingthe treadle a the cross-head a2, and with it the rods a3 a3, is carrieddownward, thus depressing the driver-bar l1., and with it the slidingblocks HH, and as they move downward the parts t' t', being depressed bythe springs J as well as theirown gravity, move with it, carrying thepocket-bar I, until the nail-pockets secured upon it rest upon the boxwhich is being nailed, as will be hereinafterdescribed, or the pinsgengage the parts it', as shown in Fig. 7. While the parts t' are thusarrested the parts II H and driverbar h continue their descent until thelower ends ofthe screws h3 h3 strike against the upper ends of thepart-s fi t', when the treadle is released, and by the operation of theweight upon its extremity it returns to its original p0. sition, and theparts H H, with the driverubar h, are carried upward, the parts t' i andpooket. bar I remaining stationary until the pins h2 engage the parts t'i at the upper portions 0f the grooves t", when they are carried up withit until their lower portions strike the pins g, arresting the movementof all the parts, when the whole machine` remains at rest until themovement of the treadle is repeated.

Upon the pocket-bar I are secured the dieholders K K K, corresponding innumber with the nail-drivers h. 'lwo forms of the die-holders are shown,Figs. 8 and l() being respectively a front elevation with the face-plateremoved and alongitudinal vertical section ofone form, and Figs. 9 andIl being respectively the corresponding views of the other. In both is ametal block with a rectangular slot cut transversely across the block,and when the cap h is fastened to the block by screws, as shown, thereis formed a rectangular eye, which may be slipped upon the bar I, and bymeans of a set-screw, K', Fig. 2, inserted, as shown in Figs. 9 and 11.The blocks may be secured firmly to the bar at any point, beinglaterally adjustable thereon, and prevented from turning upon it by therectangular shape of the bar and eye. When the form of die shown inFigs. S and 9 is used the face of the block is furrowed, as shown in thefigures.

k k are twin dies, the inner edges of which are grooved, so that whenthe dies are made to meet there will be formed a tubular orifice of theshape shown in Fig. 9,the center of which, when the dies are placed inposition, will correspond to the line e s. The dies are placed in theblock in the position shown in Fig. 8.

Springs k2 k2 are so adjusted that they bear against the dies, theirtension operating to press the dies against each other in the center ofthe block. The plate k3 is then placed in position covering the dies andsprings and scoured to the face of the die by screws. Screws are alsopassed through the circular openings shown in the dies. These screws aresmaller than the openings in the dies, thus permitting the dies lateralmovement, but are so adjusted that the inner edge of either die cannotpass beyond the center ofthe block. (Represented by the line zz.) A holeis drilled in the top ofthe block on the line z z, so that it comesdirectly over the orifice formed by the grooves in the dies.

The cap k contains an orifice which, when the cap is in position, comesdirectly over the orifice in the block, the upper portion of the openingbeing enlarged, making it funnelshaped, asv shown, thus fitting it forthe easy reception ot' the nails: There is thus a continuous tubuiaropening through the cap-block and dies, the bottom ot' which, when thedies are pressed together, is nearly closed, thus forming a pocket. Inthe form of die shown in Figs. 10 and 11 the face of the block K is cutaway, as shown, leaving a rib on each side ofthe block except for ashort distance in the upper portion.

l Z are twin dies, the inner edges being grooved, as in the dies kf k',making, when the dies are brought together, a tubular orifice of theshape indicated in the figures. Each die is pivoted through the openingin its upper part and is susceptible of vibration upon its pivot. Thesprings l l are adjusted to press the dies toward the center ot theblock, while the bearing ot' the shoulders ofthe dies against the upperend of the ribs on the block prevents the dies from passing beyond thecenter of the block (represented by the line ggz/l while they arepermitted to open laterally. The plate Z2 is secured by screws to theface of the die-block covering the dies and springs.

The cap k has a funnel-shaped opening coming directly over the tubularopening through the die, the whole thus forming a pocket, as in theother form of die.

The nail-driver consists of a punch rigidly attached to and extendingdownward from a block similar to block K of the die-holder, which issecured in a like manner by the setscrew II, Fig. 2, to the driver-barh, being so adjusted that vthe punch comes directly over the pocket.

S is a gage secured to the sliding pieces i by the vertical arms s,which extend upward from the ends of the gage and are provided with thelugs s s. When apiece is designed to be nailed it is pressed against thegage S, which determines the distance from the edge of the piece atwhich the nails will be driven.

The gage is adjustable bymeans of thelugs s', screws s2, and springs s3.(Shown in Fig. 3.) rlhe lugs are secured tirmly to the arms s, extendingtherefrom at right angles, and are IIS IZO

inserted in the openings in the `lower part ot' the pieces i, where theyare held by the screws s2, which enter from the opposite sides of thepieces 11 and engageV the lugs s' by means of holes therein threaded toreceive and retain the screws. By turning the screws the gage isadjusted to different distances back of the nail-drivers and pockets,thus determining the position in which the nails shall be driven. Theexpansion force ofthe spring s3 keeps the gage pressed back totheextreme limit allowed by the screws, so that by the mere turning of thescrews the adjustment of the gage is regulated.

s4 is a groove or slot out lengthwise of the gage. It is sometimesdesirable to have the edges of the bottom or side pieces of the boxproject slightly beyond the box. In such case the edges oi' the piecebeing nailed will project into the groove s, in whichposition it will benailed to the box, enabling the edge to be subseq uently dressed o', orotherwise, as may be desired. When it is not desired to have the edgesof the box bottom or sides project from the box a metal strip accuratelytitting the groove is inserted therein,and, the groove and strip beingdovetailed, the strip will be securely retained, and the face of thegage thus present a plain surface.

The nail-feeding attachment is supported upon the arm M, which ispivoted upon a projecting arm or bracket attached to some solid portionot' the nailing mechanism, and rests upon the end ot' the set-screw m,which is inserted in and projects through the same arm or bracket towhich the arm is pivoted, so that as the screw m is turned the arm M israised or depressed,and the nailways are thus easily and quickly given agreater' or less degree of inclination, as may be desired, theconnection t of the feeding attachment with the working parts of thenailing mechanism, as hereinafter described, being such that the changeof in` clination thus given will not affect their operation. Thenail-pan consists of the circular rim N, secured to the bottom piece, n.

Heretotore it has been customary to make the pan in one piece,thenailways being made in separate pieces and set into the bottom ot'the pan, which was grooved to receive them. This mode of constructingthe pan and nailways has been found to be expensive, as the nailwayshave necessarily to be made from steel and the bottom dressed to receivethem. In my mode of constructing these parts the nailways areconstructed in the bottom of the pan, which is made of the proper shapeand dimensions to extend beyond the rim N, at one side ot the pan, asuiicient distance to carry the nails to the proper point, as shown inFig. 4, thus avoiding the extra labor and expense involved in formingthem ot' steel and in separate parts.

The nailways a n a a consist ot' slots cut in the bottom piece, a, ofthe proper width to permit the free passage of thebody ofthe nail, butnot of the head, so that a nail may be freely suspended in the nailwaysby its head resting upon the edges of the slot. Across the end oftheextension ofthe bottom piece, n, and on each side of the extremities ofthe nailways, are secured by screws narrow steel plates n2 17.211,2 a2.The piece is dressed down until a sufticient depression is formed, intowhich the plates are fitted so as to bring their faces on a plane withthe surface of the bottom piecem. Their edges are also made tocorrespond with the edges of the nailways, which at their extremitiesare thus equivalent to being cut through steel plate. As anyinjury tothe nailways is most likely to occur at their extremities, the exposedportions are thus protected by the steel plates, which, incase injurydoes occur, can be easily replaced at little expense. A shallow grooveis sunk on each side of and near the nailway, thus leaving slight ridgesadjacent to the nailway, upon which the head ot' the nail rests, thusdecreasing the friction and enabling them to slide freely. Thisformation can be readily seen in Fig. 6. N is an apron, consisting ot' ametal plate secured in the bottom of the nail-pan and over the nailways,on the side of the pan toward the nailing mechanism, for the purpose ofpreventing the accumulation and clogging of the nails at the point wherethe nailways leave the pan. The plate is preferably made in the form ofa segment ot' a broad iiat ring, its outer and inneredges beingconcentric. On the under side ofthe apron are grooves, which coinedirectly over the nailways, accommodating the heads of the nails, andthus permitting the nails to pass under the apron and out ot' the pan.

ICO

The arms p, which radiate from the arbor P, which will be hereinafterparticularly dcscribed, consist of alternately long and short arms, tothe extremity of which are secured brushes or equivalent devices.

The operation ofthe brushes and the apron is in the manner and for thepurpose following: In the nail-pan constructed as described in my formerpatent the nails would gatherin a mass at the point where the nailwaysleave the pan, that being, on account ot' the inclination ot' the pan,the lowest point. This accumulation, entangling the nails, greatlyinterferes with their exit from the pan, and sometimes entirelyinterrupts their ilow. By the use of my device the accumulation of thenails will be upon the apron, and they will theret'ore be kept fromcontact with the nails passing out through the nailways. The brushesattached to the long arms revolve adjacently to the rim ofthe pau andpass over the apron, thus sweeping the nails therefrom and carrying themto the opposite and highest portion of the pan, whereas they slide downthe inclined bottom ot' the pan, they fall into the nailways, where theyare suspended by their heads, and,sliding down the ways,pass under theapron and out ot' the pan. The brushes upon the short arms revolveadjacently to the inner edge ot' the apron, and any nails which maypossibly have lodged at that point are IIO IIS

swept away, and the flow of nails from the pau proceedswithoutinterruption. The tendency of the nails to accumulate at thispoint, however, is so slight that it will be found in the practicalworking of themachine that a single short arm and brush will be sucientto iusure the clear operation ofthe nailways.

The apron may ot' course be made in any other form than the onedescribed, and will serve the sa me purpose; but theform described ispreferable, and will secure the best results.

On the lower side ot' the bottom piece, a, and beneath the center of thepan, is secured the cross-piece a4, (shown in Fig. 6,) containingUshaped formations, which bestride the nailways, strengthening thebottom piece and preventing any displacement of the edges of thenailways. A similar piece is placed at or near the extremities of thenailways. A small standard, o2, rises vertically from the piece n at theside of each nailway, near its extremity, with a lateral arm, whichextends over and across the nailway a short distance above it, in whicha split pin is inserted, projecting downward, and when it is desired tostop the tlow ofnails from any or all of the runways the pins areprojected into the nailways in front of the nails, thus interruptingtheir progress until withdrawn.

On the lower side of the bottom piece, n, and beneath the center of thepan, is secured the cross-piece n2, (shown in Fig. 6,) containing`U-shaped formations, which bestride the nailways, strengthening thebottom piece and preventing any displacement of the edges of thenailways. A similar piece is placed at or near the extremities of thenailways. Tubes n3 are secured to a transverse bar, so that their upperends are directly beneath the ends of the nailways, while their oppositeends are over the funnel-shaped openings of the nailpockets. These tubesare secured by pivotal connections, so that they may be swung to andsecured in any desired position, so as to conduct the nails to thepockets wherever they may be adjusted on the bar.

The finger-bar O is secured in bearings o o on the extremity of thebottom piece, a, in which it can be reciprocated. To this bar aresecured the cut-ofil lingers 0 0. These fingers consist of oblongplates, with a point projecting from one side at the extrelnityof theplate. They are arranged in pairs, as shown in Fig. 5, the pointsextending toward and overlapping each other, one point being suiicientlyin advance of the other to permit a nail in a vertical position toreadily pass'between them. The fingers are so placed that one of cachpair is beneath and adjacent to the bottom piece, n, and the other is ona plane with its upper surface, each pair reciprocating across the lineof the nailway.

An arm, O', Fig. 2, is attached to and extends downward from thefinger-bar, and is engaged by mechanism which will be described, and bywhich the finger-bar is reciprocated. An arbor, P, extends through asuitable bearing in the center ofthe nailpan. To the upper extremity ofthis are secured the radial arms p, already referred to, to theextremities of which are secured the brushes p. The arbor projects belowthe bottom of the nail-pan, an d to its lower extremity is secured theratchetwheel U, Fig. 12. A rocker-cam, U, is jonrnaled on the arborabove and adjacent to the ratchet-wheel. The outer edge of the cam formsan are, and is provided with cogs, which are engaged by cogs upon theside of the slid` ing block R, which, as it reciprocates upon the rod 1,as hereinafter described, imparts arocking motion to the cam. The cam isprovided with the spring-pawl u, which presses against and engages theratchet-wheel, and as the cam rocks upon the arbor the pawl thus givesan intermittent rotary motion to the ratchet-wheel, a retrogrademovement in which is prevented by the click fu', and the brushes P arethus rotated, as already mentioned.

a4 is arod, pivoted at one end to a rigid arm projecting rearwardly fromthe cross-head ai", as shown by the dotted lines in Fig. 2, the otherend being pivoted to one arm of the crank-lever Q, the other arm of thelever Q being pivoted to one end of the connecting-rod q, the other endof which is pivoted to the sliding block R, which reciprocates upon thefixed guide-rod i'. The opposite side of the sliding block, by means ofmechanism not shown,operatesapushpawl,which engages the ratchet-wheel onthe lower end of the arbor l).

Pivoted to the sliding block Q is the connecting rod Q, which is pivotedto one arm of the crank-lever T, the other arm ot' which engages the armO ot' the linger-bar O.

The operation of the entire machine is as follows, commencing with thefeeding attachment: The feeding attachment is adjusted at such an anglethat the nails will slide readily down the nailways, and a suitablequantity ot nails is placed in the pan. Upon depressing the treadle athe rod a4 is carried down, vibrating the crank-lever Q upon its pivot.This causes the block lt to slide upon the guide-rod and operates thepawl above described, which, engaging the ratchet-wheel on the lower endot' the arbor P, causes a partial revolution of the arbor, and with itthe arms p and brushes p. The nails are thus swept across the bottom ofthe pan, and, falling into the nailways, are suspended by their headsand slide down the nailways until they reach the extremities of thesame, when they come in contact with one of the fingers o, and theirprogress is interrupted, as shown in Fig. 5. The downward motion of thetreadle has brought in front of the nailways the fingers, which are on aplane with the upper surface ofthe piece n. Then the treadle is releasedthe weight upon its extremity brings it back to its normal position,giving the crank-levers and con nectin g-rods of the feeding attachmenta motion opposite to the one which has just taken place, and the leverT, engaging the arm O', causes it to reciprocate the bar O, and thefingers in front of IOO IOS

IIO

the nailways are withdrawn, and the ones beneath the bottom piece, a,are moved across the line of the nailways, and are so adjusted that eachfinger passes between the nail at the extremity ot' the nailway andthose behind it. The progress of the latter is thus prevented, while theformer drops from the nailway into the tube n3, by which it is conductedto and falls into the nailpocket. In nail-feeding attachments of thischaracter which have heretofore been made the finger nearest the frontofthe machine has been adjusted beneath the nailway, and would thus bearagainst the nail in advance below the point of suspension, and the nailbeing crowded forward by those following pressing against its head, itsbody would be caused to projectobliquel y backward, and thus whentheiinger-bar would be reciprocated the other finger would fail toengage it. By placing the finger directly in front of the nailway, as inmy present machine, and on a plane with the piece u, the finger beingbeveled toward its lower side, its edge bears against the nail oppositethe point of suspension and pressure, and the na-il is thus permitted toretain a perpendicular position, and the finger will not fail to engageit.

The operation of the nailing mechanism is as follows: The table B isadjusted at the proper position to allow the pieces intended to benailed together to be readily adjusted beneath the die-holders. Whilethe machine is in its normal position a piece to which another is to benailed is placed vertically upon the table and pressedback against thegage S, which is so adjusted as to bring the transverse center of thepiece directly under the central point in the pockets. The piece to benailed is then placed in position on the first mentioned and alsopressedv against the gage. A nail having been deposited in each pocket,as described, the treadle is depressed, causing the driver-bar todescend, as has been described, carrying with it also the pocket-bar I,which descends until the die-holders rest upon the box, when its furtherdescent is arrested. The driver-bar continues to descend and the punchesor drivers enter the pockets, spreading them to allow the exit of thenails,'which are then forced or driven by the punches into the box, thegrooves in the dies giving them the proper direction. The treadle isthen released and the bars hand I are raised,vand the machine resumesits original position, and another piece is placed in position fornailing.

The springs J perform an important funcltion. In machines of thisdescription heretofore constructed there has been no actuating force todepress the pocket-bar except its own gravity and that of itsattachments. As the gage S depends from the pieces it, where a box isplaced in the machine to be nailed and` pressed against the gage, theweight of the pocket-bar and attachments is frequently insufcient toovercome the resistance caused by this pressure, and the bar thus failsto descend, and the nails will not be properly driven into the wood, butby the introduction ofthe spring the certain depression of the pocketbarand'contact of the pockets with the box are insured. These springs couldbe inserted between the bars at any'point and in different modes, whichwould suggest themselves to the mind of a practical mechanic; but themode described is the one much preferable.

A peculiar and important advantage is obtained bythe construction of thedie-blocks and dies, which permit the dies to spread laterallythatis,inthe manner described. Herevtofore dies have been made for this purposewhich spread longitudinally-that is, on a line running from the front tothe rear of the machinethe result being that when the dies did not openaccurately, either from the inequality of the springs pressing themtogether or their not being adjusted in exact correspondence with thedrivers, the nail, losing its direction, would be driven to one-side ofthe proper line, and thus fail to engage the lower of the two piecesbeing nailed. In this form of die, in case of any accidental failure ofthe dies to operate accurately, the only effect 'upon the nail is todisplace it to a diiferent point upon the line in which the nails are tobe'driven and cause it to be driven through the upper and into the'lowerpiece obliquely, which only binds them the more securely.
